| 摘 要： | 对不同抚育强度下的林分的生长状况进行了研究。结果表明：林分的生长因不同的抚育间伐强度而异，强度35％～40％为宜。抚育改造可使大径木株数增加，自然枯损率降低；可加速次生林的自然演替进程；还可获得中间利用收益。抚育改造应因地制宜，正确认识，避免盲目性。

| Abstract: | The growth of stands with different tending intensity was studied. The results showed that the growth of stands was different because of different tending intensity. The tending intensity was suitable between 35% and 40%; tending improvement can increase the number of large diameter wood, decrease natural withered ratio, and promote the progress of natural succession. But it must adjust measures to concrete sites and avoid randomness. |
